OTHER REQUIREMENTS:
The oil must contain rust and oxidation inhibitor, and antifoam and antiwear agents and
must pass Vickers Vane Pump Test.
The RT-300 is factory filled with hydraulic oil for the -15
to 110
F (-26° to 43°C) range. If
significant portions of time are spent operating below 20
F (-7°C) or above 100
F (38°C),
the oil should be replaced with an extreme temperature oil. The fluid level in the reservoir
should be checked with all hydraulic cylinders retracted.
C A U T I O N
Never add kerosene or other "thinners" to hydraulic oil. These fluids have low
aniline points and consequently will cause rapid deterioration of certain packings
and seals in the hydraulic system.
C A U T I O N
Serious damage to the pump will result if it is run with the shutoff valves closed or
with insufficient oil level in the reservoir.
Observe the operation of the machine. If the oil is too cold, the machine will get sluggish
and should be warmed up further before sustained hard work is attempted. If the oil is too
hot, leakage will increase, pump efficiency will go down, system will lose pressure, and
moving parts will not be properly lubricated. Be certain machine is filled with the proper oil
for the prevailing operating temperature. If operating temperature is excessive, rapid
deterioration of the oil will result and moving parts and seals will wear more quickly. The
cause of the excess heat should be determined and corrected. Oil temperature should
never exceed 200
F (93°C).
Indications of an excessive operating temperature are:
1. Control handles become more difficult to operate.
2. Control handles stick instead of returning to neutral.
3. Excessive heat around valves and reservoir.
